  • Process for the concentration of noble metals from fluorine-containing fuel cell components
    Patent number: 8101304
    Abstract: The present invention relates to a process for the concentration of noble metals from fluorine-containing components of fuel cells, for example from PEM fuel cell stacks, DMFC fuel cells, catalyst-coated membranes (CCMs), membrane electrode assemblies (MEAs), catalyst pastes, etc. The process is based on an optionally multi-step heat treatment process comprising a combustion and/or a melting process. It allows an inexpensive, simple concentration of noble materials. The hydrogen fluoride formed during the heat treatment of fluorine-containing components is bound by an inorganic additive so that no harmful hydrogen fluoride emissions occur. The process can be used for the recovery of noble metals that are present as components in fuel cells, electrolysis cells, batteries, and the like.

  • Method for the production of compounds containing palladium(0)
    Patent number: 7615659
    Abstract: The present invention relates to a process for preparing a palladium(0) compound, comprising the reaction of a palladium compound with one or more compounds of the general formula I, II or III in the presence of a base: Term-O—{[Si(R16)(CR19CR17R18)O]v[Si(R20)2O]w}-Term ??(III). The Palladium(0) compounds are suitable as homogeneous catalysts, as a precursor for preparing homogeneous catalysts, as a precursor for preparing homogeneous catalysts in situ or as a precursor for preparing heterogeneous catalysts.
